despite all my efforts, I cannot the solve the problem.
I just want to get raster map value where I have clicked.
I can display it and get value from polygon layer but not from
raster layer concerned.
Instead I get an error message concerning line "**" :
"MapServer Error]: msQueryByPoint(): No matching record(s) found."
////raster
$heylayer ->set("status",1);
** if ($heylayer->queryByPoint($pt, MS_SINGLE, 180.0)
== MS_SUCCESS) {
// find out how many results we found
$heylayer->open();
// find out how many results we found
for ($i = 0; $i < 1000; $i++) {
// get the results we need from the layer
$res_hey = $heylayer->getResult($i);
// get our shape info from the index
$heyData =
$heylayer->getShape($res_hey->shapeindex, $res_hey->tileindex);
$hey_vars=get_object_vars($heyData);
//$heylayer->close();
while (list($key,$value)=each($hey_vars)) :
print "$key ==> $value<br>";
endwhile;
//////end rast
/////**
}
}
I will appreciate if you help me
regards
